'Application inea `January es, 1919. 's-.rial No. '273,53-5.

The invention relates to pneumatic tires rand has for its object to provide a tire of the pneumatic type, wherein the use or' an inner tube is eliminated and also exteriorly armoring whereby the puncturing of the tire is prevented.

A -further object is to provide pneumatic tire, wherein only one tube` is used, this tube being provided with a circuml`-\.rential slot on its periphery, thereby allowing the placing ol a spring ring within the tire, said ring having means whereby the eircuinferential peripheral edges of the slot in the tire tube will be securely clamped in recesses of overlapping metallic ai'inoring plates which cover the tread of the tire so as to prevent puncturing of the tire and to provide means connecting the overlapping ai'moi'ing plates to the annular spring ring, whereby the armoriug plates maybe securely' fastened to the spring ring and the edges of y the severed portions` of the tire securely clamped so as to `prevent leaking `of air through the circiun'lei'entialslit inthe tire. Also to provide the overlapping armoring plates with means for receiving a solid rubber tire, which prevents the contact ofthe overlapliiing armor-ing plates` with the ground and also increases the resiliency of h the tire as a whole. l h

With the above and other objects in view, the invention `consists of the combination and arrangement of parts as hereinafter set foi-th, shown in the drawings, describedand claimed, it being understood that changes in the precise embodiment ol the invention may be made within the scope of what is claimed without departing from the spirit of the in` if'ention. l l

lu the drawings p Figure 1 is a side elevation `of a conventional lform ol automobile wheel, showing the armored tire applied thereto, part of the tire beingr broken away.

Fig. Q 1s a perspective view of a portion ol" the tire.

Fig. 3 a collective detail4 view of the a tubeless armoring plate, spring ring and securing means, showing them in osition for placing together vand clamping tlieir adjacent parts.

Fig. tis a detail sectional view of the adjacent ends ofl' two of the'armoring plates.`

I Referring to the drawings the numeral 1` designates a conventional forni of automobile wheel and 2 the telly` thereof. Secured to the felly by any suitable means is the usual clenchcr rim 4, which is providedwith the inturned portion 5 which engagesthe.`

bead G of the tire 7. The other bead 8 of the tire receives the inturned portion 9 of a removable ring 10, which issecured to the side ol the felly by means of the bolts 11. However the rim structure and the securing means for the tire may be of any construction.

The tire 7 comprises the base l2 and side portions 13 which are substantially of the saine shape of the sides of pneumatic tires at present used. However the sides of the tire extend outwardly as at 14; thereby forming shoulders 15 and recesses 16. The` edges ol the sides are then bent inwardly toward the center of the tread so asl to forni the shoulders 17 and recesses 18, the edges 19 of the portions 20 formed by the inward bending of the sides 13 being adapted to engage each other; however they are provided with semicircular recesses which register when the edges 19 are brought together, these recesses being designated by the numeral 2l. Thus it will be seen that by providing` the tire with a peripheral slitcircnmferentially ofits tread, that it will be possible to place annular spring ring 22 on the insideol the tire. `This spring ring 22 is provided with an annular rib 23 on its outer periphery= saidrib 9.3 having shoulders 24, which are adapted to engage the recesses 18 ofthe sides bf the tire when the ring is in position with in the same. The ring 22 is alsoprovided with flanges 25 which, when the `ring is in position within the tire engage the inner sun face of the tire. y l

The armor of the tire comprises a series of` overlapping plates 26. Each plate` 26 is provided with side flanges 27 which extend around the sides of the tire and protect the same from puncturing. However the flanges 27 are provided at one of their ends with depressions 28 located .on the outside thereof, their other ends being provided with depressions 29 which are located on the inner surface @f the flanges Br this construction it Will be seen that depressions 28 and 29 Will register When the plates are arranged on the tread of the tire. The plates 26 are provided with channels 30, which register when the plates are in position on the tire and are adapted to receive a solid rubber tire 31 betiveen the fianges 32 formed by the channel 30. rllhe under surface of each plate 26 is provided with a channel 33; these channels of each plate when the plates are arranged on the tire form a circumferentialchannel Which receives the portions 20 ofthe edges of the sides of the tire.` `Shoulders 34, Which are formed by the channels 33 of each plate 26 engage the recesses 16 of the sides of the tire, While the shoulders 17 engage the corners 35 of the channel33. It `will be seen that when the ,screws 136 Which pass through apertures `27 in each-plate 216 and screw into the spring Vring 22, are set upon that channels of the various plates Will-force the portions 20 of vthe sides ofthe tire down upon the annular rib 23 and securely clamp the adjacent edges ofthe sides of the tire in the channels 33 of eachV plate so that theescape-of air from-the tire is prevented when the same is inflated, which infiating is accomplished by means of `a conventional form of' tire inflating valve 38.

Each plate 26has its corners beveled off as at 39 in such a manner that the contacting points 40 `between the plates 26, will be bsubstantially in alinement with the center of thejband forming the spring ring 22, this positioning of the contacting points between the platesrloeing necessary so that they ivill not interfere with the exing action of the spring ring 22.

`It will be seen that an eXteriorly armored tire is provided, wherein the necessity of using an inner tube is obviated, also one lwherein the puncturing of the tire is re duced to a minimum. By the use of an annular spring ring Within the tire the necessityT of extreme air pressure in the tire is eliminated, for the reason that said spring ring furnishes the resiliency ofthe tire to a certain extent. V l" The invention having been set forth what is claimed as nevwr and useful is 1.`,An armored pneumatic tire, comprit'- ing a body portion adapted to be secured to a Wheel felly, saidtire being provided with a circumferential peripheral slit, a

spring ring Within the tire and engaging Va circumferential peripheral slit, a spring ring Within the tire and engaging the adjacent edges of the split, al series of overla) m0' metallicarmorinof alates eno-avm@ b o D thetread of the tire, said plates having their overlapping portions merging into beveled off corners so as to: form contacting points ybetiveen the plates, said contacting points being substantially iiicentral alineinent With thel center of the band forming the spring ring and means connecting the plates and the spring ring forclamping the edges of the split of the tire so as to prevent escape of air fromthe tire when the same is inflated.

3. An armored pneumatic tire comprising a body portion, a spring ring Within said body portioirand provided with an annular rib `adapted toregister With an annular channel formed by channels in a series of armoring plates on the outside off the body portion and `means carried by thearmoring `plates Wherebytherib of the spring ring will clamp the tread of the tire between shoulders ofthe annular rib and corners formed by the channels of the armoring plates. j

1. An armored pnuematic tire comprising a body portion, a spring ring Within said body portion and provided With an annular' rib, armoring plates having channels on their under surfaces, `clamping means between the plates and the spring ring,

`channels in the plates for the reception of a solid rubber tire, said armoring plates contacting with 'each other at a point in central alinement With vthe center-of the ico band forming the'spring ring thereby allowing said ring to flex as the tire moves over the ground.

In testimony whereof hereunto affix my signature.
